Can anyone answer this and read carefully

C. Intricate.

Explanation:

The paragraph said that the trepanation is a "very difficult operation." The answer is not A unproductive, because this is not a pointless operation. "The operation is still used today to relieve pressure on the brain in cases of severe brain trauma." The answer is not B superstitious, because it is not belief of supernatural things or bad luck. It is an operation on the skull. The answer is not D communicative, because it's an operation, not a conversation. The answer is C intricate because intricate means very complicated and detailed. This operation is very complicated because it is removing a part of the skull. That is very hard and detailed.

Thanks for the points
